V -In the drawings, 10 is a tank provided at the top with the, filling dome 11 through which the'tank may-he filled from any suitalile source of suppLvwJoca-ted above said 12 made of flat metal bars bent to form a seat for the tank with inwardly extending feet .whieh are securedto a dcmountable frame 13. p Straps 14 pass around the tank 10 and have ears at their ends which are connected to said cradl es by the bolts 14 having locklug nuts on their threaded ends. The demountable. frame 13 is supported on the chassis or frame 15 of a truck. having the supporting wheels -1(3-'16 and'an'cngine 17 mounted :hereon by which the rear wheels 16 may be l'riven :in, any well-known mans ncr through themedium of the driving shaft 18, 'thetran: anission mechanism 19, and the transversely disposed revoluble shafts 20. The ends of these shafts 2( have secured? thereto sprocket wheels 21 .engaging with endless chains 22 passing around sprocket wheels 23st cured to and revolublo with am rear driving I'whecls 16.

The mechanism for propelling the vehi'cl forms no. p1 .rt bfthe resent invention, an

a) be 5 a. 'Qne 0 of driving mechan m is shown in Fig. 1 which it is believed is suflicient 'for an understanding of the means em loyed for driving the truck.

he engine driving shaft 18 is mounted in a tubular member 24 in which it is freely revoluble and said tubular member 24 is provided with the open coupling "Within the coupling 25 the shaft 18 has keyed or otherwise secured thereto a sprocket wheel 26 from which rotary movement is imparted by means of an endlcss chain'27 to asprocket wheel 28 loosely mounted on the revoluble shaft 29,01 a rotary pump 30.

A pump-3O is provided the inlet side of which is connected by means of a pipe 42 to a suction strainer 43 of any well-known construction, and a discharge strainer 44 of-any desired type is connected to the discharge outletof said pum by means of the pipe 45, having a 3-w'ayva ve 45 therein.

The pipes 4245 are connected, by a bypass ipe 46 having a relief valve 47 there- In. he strainer 44 is connectedby a pipe 48 communicating at its opposite end with the pipe 42 and being provided with a threewaycock 49, one branch of which is connected to a transverse pipe 50, the opposite ends of which are connected with the rear- .wardly-extendihg pipes 51, each of which has a valve 84 to controlthe discharge of material therethorugh.

' The pipe 48 is connectedto the member 53 secured to the bottom. of the tank 10 by a discharge pipe 54:, said member 53 having a.

va'lve seat 5 5 with which meets a closing drawings.

. V The valve 56 is mounted upon the lower end of a tubular valve stem 57 extending upwardly through the tank 10. Thelower end of the stem 57 has ,a hearing at 58 and er end is a revoluble rom endwise movement mounted on its 9111p sleeve '59 prevent thereon.

The sleeve is threaded to a fixed nut 60 in the upper side of the. tank 10 and .may be rotated therein by the handle'61 to move the valve 56 .to and from: its seat to regulate the dischargeof material 'from said tank.

The tumbler stem 57 extends through the hub of the handle 61 and has .at its upper end a pet cook 62 adapted to close the passage through said stem 57 when the valve 56 is 0 en. When the valve 56is closed the pet coc is moved into the position shown in Fig. 11, thereby-permitting the'air to pass through the stem 5.7 into the discharge pipe 54.

On' either side of and parallel ;to the stem 57 are distance rods 63 extending across the tank 10 and servingto strengthen the p I same. i

discharge. ipe 64 having a cutoff valve 65. 65

The pipe .45 alsohas leading therefrom a therein. he end of the pipelil is threaded material t toreceive a hose through which the contents of the tank may be discharged when it is desired to empty the tank without sending the irough the sprinkler systems. From the bottom of the strainer 44 is an-. other discharge'nozzle 66 through which the material may be drained from the strainer. The discharge nozzle is normally closed by the valve 67. The pipes 51 are provided with T-unions 68, the downwardly extending branch of each of which is provided with a pipe 69. The lower end of each pipe 69 has mounted thereon an oscillating member 70 from whicn extends the horizontal pipe 71 which is ada )ted to be oscillated through an arc of a circ e. I

To the frontend of each pipe 71 is secured a depending pipe '72 to the lower end of which is secured the oil spray ipe 7 3 ha ving an upwardly extending ri 74. The pipes 72 are connected by a distance rod by which the pipes 71 will be prevented from oscillating mdtelpendently .of each other, all as shown and escribed in another application ofv mine filed June 2, 1915, Ser. No. 32,009, of which this application is a divi slon.

'The oil spray pipes 73 are; rovided with the usualspray nozzles 77. ilach pipe 71 has secured thereto one end of a cord 78 the opposite end-of which iscoiled about an inj chned shaft 79. havinga hearing 'at 80 on the rear transom 81 of the frame 13 and provided'withan opera-ting handle. 82 at its Y outer end. The operator on his seat may turn the shaft 7 9 to move the oil spray pipes- 73 transversely fthe tank 10.

In each pipe 51 is a valve 84 which is adapted to control the passage of material through said pipe. Each valve 84 is provided with an operating arm 85 connected by a link 86 to an arm 87 secured to the oscillating shaft-'88 or 89 to which oscillator-y movement is imparted by means of the foot lever 90 or 91; Each of the shafts 88 or 89 has loosely mounted-thereon a lever 92 connected b a link 93 to an, arm 94 on a vertical oscillating-shaft 95, the lowe'r end of which has secured theretofan arm 96 con- .nected by a link 97 to. an annular member 98 surrounding the periphery of a sprinkler head.99. The sprinkler'head 99 is provided with peripheral perforations 100 in its under sidewliich are adapted to be closed by the movement of-the member 98. about the axis'of said head. The head 99 is located on the, end of a pipe 101; the o1 )posite end of which communicates with, one branch of the T-union 68 adjacent to which is a valve .02 by which the flow of material "to the head 99 may be shut. off when the oil spray pipes 7? are in; user, Between; the oil spray pipes 73 and the member-70 thepipe 71 is pro- '-vided with a three-way valve 103' operable by hand to cut off the'discharge throughthrough the flushing heads which are i the proj ecting 1O mounted on the side branch of said valve 103 and may be adjusted with the delivery slot at any desired angle.

Supported from the frame 13 by the rods 105 are the curved tracks 106 on which rests lug 107, said tracks being 1 the axis of the pipe 69 about concentrl c wit which axis the pipe 71 may be moved, car

rying with it the oil s n'ay pipe 73 and the flushing head 104. The shafts 88 and 89 may be oscillated by the foot levers 90 and )1 'or they may be oscillated bythe hand levers 108 and 109 respectively.

,The tank 10 provided at its front end with a chamber 110 from \vl'iich extend to and through a head 111 near the rear thereof a lurality of heating pipes 112 through which hot air. is ada ted to pass from the heater chamber 113 situated at the rear end of the tank 10. In the heater chamber 113 an oil heater 114 is supported on the hraekcts 115. The chamber 113 is closed b a door 116 hinged at 117 to the rear en of the tank 10 which hasa plurality of openings 118 in the side wall thereof adapted to he closed or opened by the slides 119 as shown, in Figs;3 and 5.

From the "top of the chamber 110 entends an outlet pipe 120 to carry off. the heat thei'eiu. 1

The auction strainer: 43 has secured to its oiite'r wall ayvalve 121 through which the t nk 1Q isadapted to be filled with liquid,

the valves56'and65 at thistime being closed' and the liquid pa'ssing throughthe strainer 43 and pipe 42 to the um 30, from which it issfpreedthrough t e p1 e to a-valve 122 whichv is' en, and then through-the Zpinef123 into t e top of the tank 10, the

valve 45f' having. been turned to communicam with as mp6 123.

The tank .havlng been .filled, the inlet valve 121 is closed and. the valve 56 opened,

[the valve 45* is then turned so that the liquid may flow from said tank through the strainer i3 into the pipe 42 to the pump I fromwhichi it is fenced through the pipe to and'throughdhet valve into the pipes 50 -51 to the valves 84 'wh'ich if open will permit the discharge of the liquid through the oil spray pipes 73. These pipes 73 may be moved laterally of the frame 13 by the ha dle 82, said movement being about the a ofythe depending pipes 69 and said a movement also about the pics 73 having axes. of the pipes 72 thatthe pipes 73 are always perpendicular to the axis of :the frame 13 into be moved;

When the ray 'systenris in use the but i; it is desired-t0 ya1vw65 is opened'and empty "thean whatever position they may 7 the valves 84 and 122 closed, the valve 45" of the pump, the relief valve '47 permitting this operation when a predetermmed pressure :has been 're u-hcd.

\Vhen heavy oils are used that require heat tov )ut then in suitable condition for use, the eater 114 is lighted and as the heat therefrom passe; through the pipes 112 into the chamber 110, the oil is circulated through the tan This is accomplished by turning the valv 545 so that discharge therefrom to the pipes 50 and 54 is cut oil' and opening the vah e 122, and causing the pump 30to force the oil through the pipe lfiand the ipe 123 i'nio the 'top of the tank, the oil 1 mm the pi. ie 123 being discharged in the bottom there of near the front end thereof. The oil th discharged into the tank will travel the entire length of the hot air pipes 112 and )ass through the pipes 54, 48, and 42 to tie inlet side of the pump. A constant circulation of the oil is thus created, which is continued until the oil is of the proper c nsisteney, and has a predetermined and uniform temperature throughout. 'lhlscirculation may be created either "while the vehiclcis moving or at rest; a This isof eonsiderab'li importance for it is lessen-i t1al that means should be provlded whereby oils of different kinds may be differently treated and 'tha; they be of uniform ternperature-aml cousistencyl The valve 122 is operated by means of the. lever 124 connected tothe valive stem by a lip" 4125 as slimvnin Fig,- 8'.

.On each side of the tank 10 is a reservoir.

126 adapted t9 contain kerosene or some similar oil. lrim each reservoir-126 extendsla p1pe 127 hav1ng'a yalve 128 therein and the two pi )es 127 both contact with et he pipe 12!) ex ending to the rear end of p with a head 133 having a discharge orifice 134 immediately in the rear of a bafile plate 135 seen-red, to the support136 extending forwardly from the brackets 115. ,1

A closing plug 137 i threaded to, the endof the head 133, said hlu having'aqadial slot 138 in its in ier end til The disough which any 136 l iiooumulated deposit may be d'rivenout py the flame when the plug 137 has been anscrewed sufiici'entl-y to uneoverthe' outer end;

of saidslot 138. This is of considerable importance and" should be done once eaoh: day and then the plug 137 should be again screwed into the position shown in Fig. Gof

the drawings.

Each of the reservoirs 126 is, conneeted pipes 139 to an air pump l-lOoperate-d by ahandle 141 By means 0 this pump 140 the oil in the reservoirs 126 is nnin- ..tained at a 'pressureiof. 40 lbs The amount'oi' oil passing to 114 may be regulatedb3. the needle valves 131 which, are always closed before-oommeneing to spray. These valves 131 should be kept rlosed until the fire tubes 112 are wholly covered with material in the ta'nk 10 and fmay then be opened and the combustion emitted from thedisrharge orifices 1 31 ofthe' heaters ignited.

The tank 10 ma either be filled b yvpump su tion 211$ 11 e1fiul 9f descl'ibvdi it I be fil led by any suitable 'gginviiy supply removing the manhole cover H0 and'fil ling througlrthe opening by any suitable conducting hose or pipe.

' \Vhen using. heated; material in. the tank -10 it important that the tank should'not be quite fullas some space must be allowed for expansion n- \Vhen the tank .10 has been filled bv means of the pump 30 the latter. is stopped and the valve 121i elosed. r lVhen' ciroulat ing the material in the tank 10 the valve 56 should be \videopen and the I pump 30 startedat a moderate speed. 'T-he pump is kept running until the material; is

thoroughly agitated to a proper temperature ,as -.slio\vn by a thermometer provided for Y this purpose; said thermometer not being shoivn in the drawix'igs'as it maybe of any \vollkno\vn eonstruvtlon and'forms no'part of the presentinvention. The location of the delivery end of thelpipe 123 M the hotto i'r ofjthe forwardfend'lof the t'anl'ii s of great iiuportanre asby "thismeans the oil passing through the pip'o 123 along thef'upper side of the tau'k is gradually .lieatedyaiul when diseharged into the bottom ofthe tank it. will flow toward the reareud of the tank in 'oontart with thehot ail-"tubes and then I list above the illllitS'hI 'ld 'flOW toward the front end of the tank. Qhronstant.c'irlulation of the material s thus maintained until the temperature of all the material is uniform.

' 1 The -.b l unorsare then eitinguished; and

the valve -15:opened,permitting the mate- I rialflto be forced by thepump 30 through the oil spra'y pipes-r 3.

Whenever it 1s necessary to stoput'he distribution" of the oil for any length'of time before the tank is entirely emptied, the valve the jll uters 56 is closed and the vent cook (i2 is opened. 'lhefmlves 8+ are then opened and the pump 30 isrun until the piping system is entirely free from material.

The riroulating valve 122 is then closed and the kerosene oil valve 142. is opened,

allowing a jet'of kerosene oil toenter the pump and piping system, and thepump 30 lskept running until the kerosene ol'l forced through the piping. system has thoroughly 'oleuredthe same.

The drain rorks'fii' are then opened t'opermit the draining of the strainer-casings 43 'llnd -H. A pipe 143 leads from the. top of the tank 10 with S. discharge. end at I l-lbeneath the tank. .This provides a" moans .whereby any excessive amountof material in the tank will be discharged upon the road over vvhieh the truck is traveling, and will prevent any of this material being scattered over the outside of the tank 'or'onthe operating parts.

ll'hen it is desired to spray by means of a liose','thehose may be attached to tilt unloai'ling ro'ek 64 and the valve 5 opened, the

pressure bring, regulated by the valve 122 (-oi'itrolled b'vthe lever 124. I

\l'heu it is desired to draw off material'in buckets, the valve (35 is opened and the bark; ets tilled through the dischargepipe 64.- 'The relief valve 47 \vhrn set for th proper pressure should not be hangedfi The door 116 is provided with a draft opening 14'? therein. which is adapted to be elosed' when desired hy means of the plate 148. hinged at its upper edge as "indicated at H9 and adapted to be supported in open position by meansof the (rhain 150.

lOO

'hen the material in the tank 10 is heavy obviously ill harde'n'as soon it becomes -old. a

This isof" considerable importance as it is necessary to keep the pipes "clear and onlyj permit the heavy oils to pass through when they have the proper; consistency and temperature and. under pressure created by the pump 30;

: \Vhen the pump 30 is not in operation the valve 45 may be turned also into position .to cut oil thematerial fromghoth the pipes :4 and 123. v I

\Vhen the valve'lfi" is turned to direct the material into the pipe IQ-i-and the valve 122 rlosed the valve lidmay. be: opened and the material discharged through the )ipe (H.

The valve 122 may be used to regu late'the pressure of the material passing through the pipe system, it beingobvioustt'lmt if said valve is partly open a portion of the material will* "pass through the valve 122 and will be under t valve 47.

One of the reservoirs 126 must be filled with kerosene oil or some equivalent which may be used in the heaters 114, but in some cases where certain kinds of material are being used in the tank 10, kerosene oil is not a suitable flux, and in this case the other reservoir 126 ma be filled with some other flux which may used when the pipe systern is to be cleared.

Among other advantages -of the present invention it will be noted that the material 4 chain 27 am, disconnecting thd securing eis heated'by means of a dry heat passing through the hot air pipes 112 and that during the heating process means is provided.

for keeping up a constant circulation of the material in the tank, the various portions thereof coming successively into contact with the pipes 112 until the entire contents of the tank 10 have a uniform temperature.

In yiew vof this constant circulationof the material there is no danger of burning i the material. 3

The heaters are under the constant control of the operator and askerosene oil is used there is no such delay in heating the material as would'be the case if steam heat were used and it'is obvious thatheat of any required temperature. is available at once ardless of weather conditions.

ith thisv device -there are no the material may be heated while the truck is on the wa to the pl'acewhere the spraying is to be one.

An% volume or. temperature of material may e evenly and uniformly distributed by the apparatus and said apparatus is adapted for use in distributing either cold or hot material. a

Means are provided whereby the entire pipe system ma be thoroughly cleared of oil and the tanr may be filled with water and the apparatus then used for watering the streets.

It is alsopossiblc by disconnecting the bolts 14 to reii'roy e the demonMable-frame 13 with its tank :md piping system from the chassis 15 and then hse the trucldfor any other desired.' 'iurpose. ,When it is desired to flush the streets instead of spraying them, provision is made for cutting oil the spraying devices and permitting the oil to be discharged through flushing heads adapted to be swung in a horizontal plane with the. delivery any desired angle,

delays as ends at i There is at no iime'any internal pressure within the tank, thereby making it possible to use athinner sl ell than would be the case in tanks in which steam or other pressure is used. All the PIKSSUIG required is obtained by means of the r )tary pump 30 which may also be used for l( ading.

It is believed th it the'operation and many advantages of th s invention will be fully understood from, the foregoing description.

Havingthus described my invention, I claim: y

1. In a device )f the class described,'the combination of a tank adapted to contain heavy oils for use on roads and having a chamber at one M d; a heating compartment at the opposites: 1d; a device in said compartment for cres ting dry heat; a plurality ofhorizontal tubes within said tank ex tending from s e id compartment to said partment for creating dry heat; a plurality of horizontal tubes within said tank extendingfrom said C0! ipartment to said chamber and through Whiuh said dry heat is adapted a i to pass; means fcr delivering the heavy oils to said tank at a point near the bottom thereof and near its forward end; and means for discharging said heavy oils from the bottomof the ear end oi said tank.
